. To all whom it may concm:

Be it known that 1,' W1LLIAM J. LILLY, a subject of the Kin of Great Britain and a resident of Butte, n thecounty of Silverbow and State of Montana, have invented a new and Improved Pump-Plunger, of which the following is a full, clear, and exact description.

My invention relates to pump plungers for general use and is particularly adapted for pump plungersemployed in mnes for the purpose of removing mine water and other liquids containing acids.

More partic larly stated, I seek to provide a pump plunger consisting mamly of acid-proof material so arranged as to be efi'ective in all respects required by a pump plunger and yet possessing great strength coupled with simplicit --the external portion of the pump plunger being not' only very smooth but impervious to the corrosve action of acids and the like with which the water to be pumped may be impregnated.

A practical embodiment of the invention' is represented in the accompanying drawings 'forming a 'part of this speccaton, and in which like characters indicate like parts.

Figure 1 is a section on the line l-l of Fig. 2, looking in the direction of the arrows, and shows my improved pump plnnger; Fig. 2 is a plan view of the pump plunger shown 111 Fig.

view showing in elevation a portion of a metallic core formin a part of my device and difi'ering from the form of core shown in Fig. 1; Fig. 4; is a detail View showing, partly in section and partly n elevation, another form of core, used for substantially the same purpose as the forms shown in Figs. 1 and 3; and Fig. 5 is a -fragmentary elevation showing still another form of core, used for the purpose above ndicated. A body member 6 having the form of a hollow cylinder is made, in this instance, of porcelain, though it may sometimes be made of glass, china, stone or an stance acted upon but slightly, f the acids contained in water. member 6 is provided with an inner face 7 which is roughened. If the body member be made of 'porcelain it may be roughened by forming its inner face of crushed porcelain and casting the rest of the body member around this portion. The body member is provided at one of its ends with at all, by

other sub- The body a projection 8. This pro ection 's merely for the purpose of enabling the body member to be handled readily for purposes of grndi'ng itssurface.

The external round surface 9 and the upperend 10 of the body member 6 are ground. I provide a metallic core 11 hav-- ngan annular flange 12 integral with it,

these parts thus constituting a single member. This member is provided with holes 13; in this instance, two in number.

i I provde a number of bolts 14 each having threaded portions 15, 16, and connect these bolts with the flange 12 by inserting the threaded portions 15 in holes which are drilled in the flange 12 and threaded. A recess 17 is provided for accommodating a pro ection usually found on the end of a crosshead. The core 11 is provided with a number of grooves 18. A quantity of plastic material 19 capable of hardening and setting is poured through the holes 13 so vas to fill the grooves 18 and the space between the core 11 and the inner face of the body member 6. The material used for this purpose may be sulfur heated to a molten state, or it may he any suitable kind of cement capable of setting. The material 19 thus' holds the core 11 rigid relatively to the body member 6. A small portion 20 of the plastic material may creep out between the ground end 10 and the adjacent flange 12, as shown at 20 in Fig. 1.

In some instances the core is given the form shown at 21 in Fig. 3; that is, it is provided with slots 22 each of arcuate form, as shown.

Sometimes it is desirable to give the core the form indicated at 23 in Fig. 4. In this instance, it is provided with shallow holes 24: extending radially inward.

If desired, the core may recei e the form It is here provided with bosses 26 extending radially outward.

hen the core has either form shown in Figs. 3, 4 or 5, it is very easily anchored by the 'plastic material 19.

Instead of using the bolts 14: any other appropriate means may be employed for connecting'the plunger to the crosshead of the pump.

I do not limit myself to the precise construction shown as variations may be made therefrom without' departing from the spirit of my invention, neither do I limit myself in all instances to any particular material to be employed though I find that vitreous material is especial y adapted for 'the body member 6.

members made of acid proof material, a core extending into the said body member and spaced therefrom, and a plastic material capable of hardening and located in the space between the core, and the body member, the said core having a flange at its top and openings leading to the said space, for the admission of the plastic material.

2. A pump pluger conprising a body member having the form of a cylinder and made of acid proof material, a core extending into the said cylinder and spaced from the inner surface thereof, the core having an integral flange at its upper end extending over the top of the body member, the top of the core and flange having a circular recess fol-med therein, and openings leading from the bottom of the recess to the space between the core and body member, and binding material filling the said space and engaging the body member and the core, the said binding material being admitted through the said openings.

3. A pum plun er, comprsin a bod member having theeneral form o f a oylin der and provided externally and at the upper end with a ground surface and internally with a roughened surface, said body member being made of porcelain, a metallic core extending into said body member and provided with anchorages, and a. binding material located within said body member and engagng the inner surface thereof and also engagng said core, said core being further provided at its pper end with an annnlar flange and with a -eeess, the core having holes leading from the reeess for admitting said bindig material.

4. A pump plnnger eomprising a body member having the toi-m'et a cyhnder and made of vitreous aeid-p'oof material, the outer surface of said member being ground and the inner surface being 'oughened, a metallic core extending into the said cylinder and spaced from the, inner surface there-- of, the said core ha ring an integral flange extending over the top of the body member, means Secured' to the flnnge for connecting the plunger to the cross head of a pump, the said core having` grooves formed therein, a binding material within said body member and engaging the ronghened inner surface thereof and the, g'ooves of said core to hold the core rigid relatively to the body member, the said core having a. recess in its top and holes leading from said rccess to admit the binding material to the space between the body member and the core.

In testimony whereof I have signed my name to this specifieation in the presence of two subscri'bin; witnesses. I
